Jim al-Khalili talks to the astronomer Jocelyn Bell Burnell about missing out a Nobel Prize, sexism in science and a strange smudge in the data from a radio telescope. While others dismissed this smudge as insignificant, Jocelyn revealed a series of strange flashing signals. They might have been evidence of faulty radio telescope or even messages from a little green man; but Jocelyn thought otherwise and her determination to get to the bottom of it all, led to one of the most exciting discoveries in 20th century astronomy, the discovery of pulsars, those dense cores of collapsed stars.

Allison-Levick Memorial Lecture: The accelerating universe
Dark Energy is causing the expansion of the universe to speed up – and not to slow down as everyone expected. This discovery overturns astronomers’ ideas about the history and the fate of the universe. Professor Brian Schmidt describes the discovery that won him the Nobel Prize in Physics last year.

Neil deGrasse Tyson On Exploring Cosmic Frontiers
http://www.sciencefriday.com/program/archives/201203024
Many of us spend more time at our desks than anywhere else. Astrophysicist Neil deGrasse Tyson takes us into his office at the Hayden Planetarium in New York City for a tour of his office, in the fourth of Science Friday’s Desktop Diaries series. From a Saturn lamp Tyson made as a kid to his van Gogh pillow, Tyson has a lot of universe-themed paraphernalia. Tyson highlights some of his collection, and talks about what his journey to science stardom has been like.

Saul Perlmutter: Exploring Supernovae Leads To Physics Nobel Prize : NPR
Astrophysicist Saul Perlmutter is part of the team that was awarded the 2011 Nobel Prize in physics for the discovery that the expansion of the universe is not slowing down but is accelerating. The results of that research suggest the universe is filled with dark energy.

Singularity University Lectures: Science Searches for ET by Seth Shostak
Seth is the Senior Astronomer at the SETI Institute, in Mountain View, California. He has an undergraduate degree in physics from Princeton University, and a doctorate in astronomy from the California Institute of Technology. For much of his career, Seth conducted radio astronomy research on galaxies, and has published approximately sixty papers in professional journals.
He has written several hundred popular magazine and Web articles on various topics in astronomy, technology, film and television. He lectures on astronomy and other subjects at Stanford and other venues in the Bay Area, and for the last six years, has been a Distinquished Speaker for the American Institute of Aeronautics and Astronautics. He is also Chair of the International Academy of Astronautics’ SETI Permanent Study Group. Every week he hosts the SETI Institute’s science radio show, “Are We Alone?”
Seth has edited and contributed to a half dozen books. His most recent tome is Confessions of an Alien Hunter: A Scientist’s Search for Extraterrestrial Intelligence.

Mysteries Of The Sun
Oh, yon flaming orb. Every day, Helios’s chariot carries you across the sky.
Well, perhaps not: but the 27 million degree star that rules our every waking hour actually has a beating heart. Well, a pulse.
Anyway, it also generates a kajillion fascinating facts — did you know you get more Vitamin D from ten minutes in the sun than 200 glasses of milk?
We explore stories of the star, its eclipses, storms, shelf-life and why somewhere over the rainbow, it’s way up high.

Why Not to Fear Black Holes with Astronomer Ian Morison
Black Holes seem to have bad press that is largely undeserved. This lecture with professor Ian Morison explains what Black Holes are, and how we can discover them even through they can’t be seen.
This program was recorded in collaboration with Gresham College, on October 27, 2010.
Gresham Professor of Astronomy Ian Morison made his first telescope at the age of 12 with lenses given to him by his optician. Having studied Physics, Maths and Astronomy at Oxford, he became a radio astronomer at the Jodrell Bank Observatory and teaches Astronomy and Cosmology at the University of Manchester.
Over 25 years he has also taught Observational Astronomy to many hundreds of adult students in the North West of England. An active amateur optical astronomer, he is a council member and past president of the Society for Popular Astronomy in the United Kingdom.
At Jodrell Bank he was a designer of the 217 KM MERLIN array and has coordinated the Project Phoenix SETI Observations using the Lovell Radio Telescope. He contributes astronomy articles and reviews for New Scientist and Astronomy Now, and produces a monthly sky guide on the Observatory’s website.
